11 Alarms and faults
Alarms are shown in the alarm line of the display in the form of
text. The text is displayed with a particular background color as a
function of alarm priority:
If more than one alarm is active, the device responds as follows:
• Multiple alarms of different priorities: The device displays the
alarm with the highest priority. Alarms with a lower priority do
not appear until the higher-priority alarm is no longer active.
• Multiple alarms of identical priority: The device displays the
alarms in rotation.
• Technical alarms predominate. They cannot be muted.
Technical alarms are generated if no ventilation by the device
is possible.

fatal or irreversible patient injuries or
of device faults.
Yellow Medium priority
Medium-priority alarms warn of
immediate reversible patient injuries
or of minor device faults.
Turquoise Low priority
